Bursting Fracture of Balloon-Expandable Stent and Pseudoaneurysm Formation in the Left Common Iliac Artery and Endovascular Treatment With Graft Stent

초록

Purpose: To report successful endovascular treatment of a previously implanted balloon-expandable stent bursting fracture with concomitant large pseudoaneurysm formation in the left common iliac artery (LCIA).Case Report: A 72-year-old man had been previously treated with balloon-expandable stents for severe stenotic lesion in the LCIA and left external iliac artery. Seven years later, the patient complained pain in both lower legs and back. Angiography demonstrated a 3.5-cm-sized pseudoaneurysm in the LCIA with embedded metal fragments around the lesion. An endovascular treatment was selected using a limb extension graft for endovascular aortic aneurysm repair. The device was successfully deployed, and no endoleak was observed. At 1-month follow-up, computed tomography scan confirmed patency of the implanted stent graft devices in the LCIA and the absence of any endoleak.Conclusion: Endovascular approach using a limb extension graft stent for endovascular aortic aneurysm repair can be used for treating stent fracture-related pseudoaneurysm in the common iliac artery.
